Warning: This article contains spoilers for Deadpool and Wolverine.

You might have thought the dust is now settling following the highly-anticipated release of Deadpool and Wolverine, but fans of the Marvel heroes still have plenty of easter eggs to sink their teeth into.

Viewers have been trying to decipher all of the covert messages and hidden cameos since the trailer dropped, so the detective work has been taken up a notch now that the film is available to watch in cinemas.

You probably need to watch it a couple of times to really get your head around all of the tidbits that have been snuck into Ryan Reynolds' labour of love though, as there is an absolute boatload of them.

Deadpool and Wolverine boasts an incredible collection of cameos from some of the biggest names around, including massive Marvel returns, as it seems that every Hollywood star wanted a piece of Wade Wilson's action this time around.

Even Emma Corrin, who makes their MCU debut in the new blockbuster while starring as Cassandra Nova, told LADbible that the cast 'never knew who they were going to bump into on set' as it was that chock-a-block with famous faces.

King Charles' name was even bizarrely thrown in the mix for a Deadpool and Wolverine cameo.

However, it's the scene where the Deadpool corp arrive which has really got people talking, as a series of superstars lent their acting talents to the project.

As we all know by now, Blake Lively became Lady Deadpool and two of her and her superhero husband's children, Inez and Olin, voiced Kidpool and Babypool - so it was something of a family affair.

But Reynolds didn't just stop at recruiting his nearest and dearest, as one of his famous friends also offered up their vocals to Deadpool and Wolverine... but a lot of fans missed this A-list cameo due to being so engrossed in the movie.

Which is why were here to clear things up for you - no, that wasn't a fever dream, as I can confirm you did hear Matthew McConaughey's signature drawl when Cowboy Deadpool swanned up on screen.

It's a blink-and-you'll-miss-it moment for your ears though, as he literally has one line - but it at least give fans who have long wanted the Interstellar star to join the MCU a little taste of what he would be like.

Taking to social media to confirm their suspicions, one person said: "Was I the only one who recognised Matthew McConaughey's voice in Deadpool? Ain't heard anyone mention it yet."

Another wrote: "It's so odd they have him but never actually reveal it is him unless you can recognise his voice."

A third added: "No way Matthew McConaughey was the southern cowboy Deadpool in #DeadpoolAndWolverine."

While a fourth chimed in: "I can’t believe Deadpool and Wolverine is the closest I’m gonna get to Matthew McConaughey in a comic book movie."

McConaughey's name was supposedly put forward for 2016's Doctor Strange, which Benedict Cumberbatch ultimately starred in, while the actor also reportedly turned down a gig in Guardians of the Galaxy Vol. 2 as Ego the Living Planet.

So for now, you're going to have to be satisfied with seeing the star stomp over in his boots as the gun-slinging Deadpool variant and saying a single sentence.

Deadpool and Wolverine is in cinemas now.
